Paint Mode Settings

This dialog is used to set up the scalable paint modes such as Brighten (see menu Mode).
You can also change mode scaling real time if you use a pressure sensitive pen. In that case you should have a look
at the pen pressure settings.

Dither can be enabled with every paint mode and you can define the pattern here.
The value can be between 0..255 where 0 is no dithering and the larger
the value becomes the more color is used for dithering with the foreground color.
When using the inverse mode then the value has the inverse meaning.
Below the dither slider you can set up different dither patterns for quick selection.

Formula: Select a defined formula to be used to calculate the paint mode operation. By using Add or
Edit you enter the formula editor to add new formulas or to edit the current one.
There are the following predefined formula samples built in:

Diagonal Gradient

Draws 45° lines using the current gradient

Single Step Shade

Works like the normal shade mode, but it only shifts one color slot per drawing step.

Gradient Brighten

Increases/Decreases brightness, but uses the best matching color of the current gradient.

Scanline

Fills every second pixel line with the given color.

Gradient Invert

Inverts the color within the current gradient. Inversion means that the first color of the gradient becomes the last one and vice versa.

Conditional Paint

Draws the selected colors only when the brush pixel matches the pixel within the image.

Exclusive

Locks pixels of the "other" color selector. That means if you have white as foreground color and white as background color then the left
mouse button draws white where there is no black. The right mouse button draws black where there is no white.
